New renders of the supposed Zune HD have emerged, so take these photos for what their worth.

According to wmPowerUser, the new Zune HD will include a capacitive touch screen, wireless sync, a multi-touch OLED screen with a 16:9 ratio, TV out, support for 3D Xbox games, and of course, HD playback. It will also come in 16 and 32GB models, and set to launch sometime in September

That sounds like one helluva an upgrade. Assuming that all of the above is true, will it be enough to challenge the iPod Touch?
